Pollution of water by organic and inorganic chemicals is of serious environmental concern. Sugar industry is one of the biggest consumer of water, and can also introduce serious pollutant to the environment. Water utilities use granular activated carbon (GAC) to remove variety of contaminants like COD and BOD. Which are well studied during this study, whose results followthe Freundlich and Langmuir adsorption isotherm.GranularActivated Carbon (GAC) prepared fromwood and nutshell charcoal with specific surface area of 10.50 cm2/gmand particle size 1.08mmis used as an adsorbent to the combined waste water of Sugar mill at room temperature. The different dosage ofGACis kept in contact for 24 hours, then theywill analyzed before and after treatment.
